According to TransCanada Corporation, the U.S. Department of State has signed and issued a Presidential Permit to construct the pipeline, which would send Alberta bitumen to U.S. refineries.

“We greatly appreciate President Trump’s Administration for reviewing and approving this important initiative and we look forward to working with them as we continue to invest in and strengthen North America’s energy infrastructure,” Russ Girling, TransCanada’s president and chief executive officer said in a release.

The project was first proposed in 2008 and while it received approval from the Canadian government, then President Barack Obama vetoed a bill that would approve construction in 2015.

During his campaign, Trump announced one of his first plans in office was to kickstart Keystone.

In a statement, Premier Rachel Notley says this project is going to support nearly 6, 000 jobs during construction and over 400 full-time jobs in Alberta.

“While Keystone XL progresses, we are also going to continue our work to make sure we can get Alberta’s resources to Canadian tidewater – creating jobs, helping our energy industry grow and diversifying our export markets.”

With Friday’s announcement, TransCanada says they’ll discontinue its claim under Chapter 11 of the North American Free Trade Agreement and will end its U.S. Constitutional challenge.

TransCanada adds they’ll continue to engage with key stakeholders in Nebraska, Montana and South Dakota to obtain the necessary permits and approvals to being construction.
